SPECIFICATION forming part of Letters Patent No. 650,329, dated May 22,1900.

Application filed April 2 8, 1 8 9 9.

To @Zi wiwi/'t it may concern-.-

Be it known that I, JOHN KREMSER, a citi; zen of the United States ofAmerica, residing at Duquesne, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inLowering Devices; and I do hereby declare the follow-V ing to be a full,clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention has for its object the provision of certain new anduseful improvements over my former patent on locomotiveelevators, No.602,457, granted to me April 19, 1898.

The object of my present invention is to vfurther improve my elevator byadding to it a turn-table, a crane, a means of rotating thelocomotive-wheels when setting the valves, and a means whereby theelevator is operated by belt-power.

Vith the above object in view the invention finally consists in thenovel construction, combination, and arrangements of parts, as will behereinafter more specifically described in detail.

In describing the invention in detail reference is had to theaccompanying drawings, forminga part of this specification,and whereinlike numerals of reference designate like parts throughout the severalviews,in which- Figure 1 is a side view of my improved elevator, Fig. 2is a plan view of the same. Fig. 3 is an end View of the turn-table.Fig. 4 is a perspective view of the end of one of the elevator-beamsReferring to the drawings, the numeral l designates upright or verticalcolumns, within each of which is arranged a vertical screw, such as 2.The bevel-wheels 3 are made fast to the upper ends of these screws atthe tops of the columns. Bearings 4 are made fast tothe tops of thecolumns, and Within these bearings are loosely iitted the shafts 5,which have the bevel-pinions 6 secured to them, which mesh with theaforesaid bevel-wheels. A horizontal shaft 7 extends across from onecolumn to the other and is loosely mounted in bearings 8 at the tops ofthe columns, andv this shaft is provided with the miter-wheels sain No.714,915. (No model.)

9, which mesh with similar miter-wheels 10 upon the aforesaid shaft 5. A

The I-beams 11, upon which the rails 12 of the elevator rest, are eachprovided at their ends with a plate 13, which is made fast to the beamsand extends over and around the vertical screws and rests upon largenuts 15, which are 'arranged upon the said screws. Between the aforesaidI-beams 11 is secured the spider 16, having the bearing-pin 14projecting upwardly therefrom, and upon this pin is pivoted theturn-table 17, having the rail-pieces 18 secured thereon. Looselyarranged between these rail-pieces are the shafts 19 and 20, upon whichare mounted the wheels 2l and 22. One end of the shaft 20 projectsthrough the rail and is provided with the bevel-pinion 23, which isadapted to engage with the bevel-wheel 24 upon the horizontal shaft 7. Asuitable lever 25 is arranged in connection with this shaft 7 for movingthe aforesaid shaft one way or the other and causing the miter-wheels 9and 10 to be disengaged when it is desired to engage the bevel-wheels 23and 24. A belt-pulley 2G is provided upon the said shaft 7, whereby itmay be coupled up to suitable power. The ends of the rails which leadfrom the switch or track are made fast to the tops of the columns by thebrackets or chains 27.V

By applying power to the belt-pulley 26 the elevator is raised orlowered, as desired, and in replacing a pair of driving-wheels under alocomotive and in order to turn them to the desired position forcoupling up with the drive-rods or the setting of the valves the wheelsare run-onto the turn-table, as shown at Fig. 1 by the dotted lines, insuch position that the small wheels 21 and 22 willV engage with theanges of the driving-wheels. Then by moving the lever 25 themiter-wheels 9 and 10 are disengaged and the bevel-wheel 24 is broughtinto mesh with the bevel-pinion 23.

Power is then applied to revolve the shaft 7, which in turn will causethe drive-wheels to revolve by the action of the wheels 21 and 22, untilthe drive-wheels reach the desired position. In removing the wheels thetable is turned and the wheels run ont within reach of the crane andremoved.

For-the purpose of raising and lowering the IOO truck and locomotive.wheels I have provideda crane, which consists in suitably attaching "arope or chain 30 to the under side of the spider 16. This rope or chainis then passed down under a pulley 3l, arranged at the foundation,thence upward and over a bar 32, which is laid across the tops of thestandards 33, and is provided at its end with a suitable hook 34. easilybe raised or lowered by the elevator. I have also provided a drum 35upon the shaft 7 for operating a suitable overhead crane. This drum isloosely fitted upon the shaft and provided With a clutch 36,'which byany suitable means may be caused to engage with the Y.

catch 37, which is fast upon the shaft, l,when it is desired to rotatethe drum and operate the crane.

If it is desired to increase the height'of the elevator, I have shown anadditional section 29 of an I-beam in connection with the I- beam ll atFig. 4. This section is secured between each end of the beams and theplatesy 1.3.

Having thus shown and described my invention, what I claim as new, anddesire to secure by Letters Patent, is

'1. The combination with a series of hollow columns having a verticalscrew arranged therein and provided with a nut,- of a plate mounted onthe said screw and supported by the said nut, I-beams supported by thesaid plates, rails mounted upon the said beams, a turn-table suitablysupported by the said libertins, bevel gear-wheels secured to the top ofsaid screws,- a shaft provided with bevel= pinions connecting together apair of the said screws, and means connected to the said shaft foroperating the same thereby lowering the rails and said turn-table,-substantially as de; scribed 2. The combination with the elevator asdescribed, of a turnstable, frictionwheels 2l and 22 arranged upon thesaid turn-table to engage withl and revolve the locomotivea Wheels, anda means whereby the said wheels are revolved, substantially as shown anddescribed.

By this means the wheels may' 3. The combination with the elevator asdescribed of a turn-table, friction-wheels 2l and 22 arranged upon thesaid table to engage with locomotive-wheels, the belt-pulley 26,arranged upon the shaft 7, and a means whereby power is transmitted fromthe said shaft 7 to the said friction-wheels, substantially as shown anddescribed.

4., The combination with a series of hollow columns each having avertical screw arranged therein and provided with a nut, of a platemounted on each of said screws and supported by the nut, I-beamssupported by said plates, rails'mounted on said beams, a turn-tablemounted on the said beams and supporting the said rails, operating meansfor said table, bevel gear-wheels secured to the top of the said screws,and meaIlS connected to the said wheels and operative for lowering theI-beams, substantially as described.

5. The combination with the elevator and turn-table, of the rope orchain 30 secured to the said turn-table, a stationary pulley-block suchas 3l arranged below the said table, the standards 33 and bar 32, allarranged and adapted as and for the purpose set forth.

6. The combination with an elevator, of a turn-table suitably supportedthereby, means carried by the said table adapted to revolve the wheelsof a locomotive or other vehicle, and means adapted to be connected tothe said revolving means for operating the same, substantially asdescribed.

7. The combination of an elevator, operating means therefor, aturn-table carried bythe said elevator, means for revolving locomotiveor other wheels mounted thereon, operating means therefor, and suitableconnections between the same and the operating meansof the elevator,substantially as described.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.
